Be it linovfn 'that l, FREDERICK C. @wie IiUuv, a citizen of the United ideales, residing in Hillsdale, in the eouny of Bergen and State of New Jersey., have invened ceiain new and useful lmprovcrnents in Machines for lllaking Shingleitrips, of which the iollowirul` is a specification.

This application is a oontinuaion of an original application vfor' United @lates Lela ters Patent filed hy ine ou July 14, Serial No. 39,8%, and allowed under dale of April lil, 1919; which application was reneuf'ed after being alloucd to lapse under date of lune el, 1920, Serial lilo. 386,579 and now stands allowed under date of June l, .1920.

lThis invention rela'lves 'to a machine for producing roolng' sii-ips and more partie-w larlylo a mechanism adapl'ed for producingr flexible waterproof rooling,y strips having de signs cul, ourl along one edge of the srip, these strips being; eonneced to the iool' in overlapping courses to expose the edges from which the cul/ours are made.

Among the salient ohjccle the invention are o provide a machine hy Wliic i a plurality of Tooling or shingle strips can he pro duced from an ordinary sheet of prepared roofing` and in such manner as 'lo utilize the original outer or selvage edges of he sheet as lhe lower or exposed edge ol' the roofing srip when laid. Other objects of the invention are 'fo provide a machine Jfor auoniatically cutting and removing lhe cutout portions along the edge of the strip, the eutouts being entirely severed from from the sheet before forcingr them ourl of the plane of the main body of ehe sheet; to provide means for automatically ejecting the cul-outs of the strip when severed; "so provide a construe 1tion in which a continuously rotating head can be employed to produce a plurality olf the strips`r 'he cutout at one edge,l however, being' independent of the cutout al; the op posite edge; to provide a construction in which removable knives can be employed and 'the entire mechanism readily changed or adjusted; and in general eo provide an iinproved machine for producing roofing of the character referred to and rewinding the strips as formed,

ln llie parl'icular embodiment of my invention shown. in he drawings, ll employ a power driven machine which is provided with one or. more cutter rolls or heads l, each of which carries a plurality of cutting meinhers 2, adaped upon rota'lzion of the cutter head to compleaely sever strips from the marginal portion olE a coiitinuously advancingv sheer f3 or flexible roofing, which is fed, le ehe sheet passes' over an idler roll il. over lhs idle roll, ehe cutting inenljers 2 are hrougrh;I against the portion of the sheet 'which ispassinpr over lelie lace of theroll, and cui out strips Yfrom the marginal porlions thcreo The sheet is drawn across the idler roll by means of drawing ofi" rolls 5 and 6., and alici' passing1 through the drawoff rolls, it is conducted across a feed bed to a pair of slitling rolls 7 and 8, aferruf'hich it is' rewound into a roll The idler roll es is mounli-ed .in the side frames ll, and *which are connected at their lower ends by series of ties or cross braces 13. flrdjustahly mounted in Vthe end plaies ll and l2 is a carrier roll` lll held in frictional contact ivih the idler roll 4 hy rneans of an. adjusring screw l5, which raises or lowers it accordingly as the Worin gear 16 is adjusted lo the right or left. The drawing olii rolls and 6 are mounted in the suppleinenal iframe members l? and 18 which are secured by bolts 19 and 2O to the end plates ll and l2, and the roll 5 is springpressed toward the roll 6 by the action of springs 2l and 22 so as 'to have suliicient frictional Contact with the sheet to draw it along across the idler roll.

There are preferably a pair ol the cutting heads, l each' carrying a. plurality of the l cutting members 2 and adapted to operate upon the opposite edges of the doublewidth sheet, and the cutter heads are bolted to a shaft 23. which 'is journaled in the end plates ll and l2, and is provided at one end with a gear wheel 24. The end plates 1l and 12 have bearings 25 in which the main drive shaft 26 is journaled,'this shaft being provided at one end with a bolt wheel 27 and at its opposite end with a gear wheel 28. The connection between the gear wheel 28 on the drive shaft and the gear wheel 24 on the cutter head shaft is as follows:

Mounted on the end plate 11 is an intermediate gear 30 which meshes with the gear wheel 28 and a gear wheel 3l secured to the carrier roll shaft 32. This last mentioned gearvwheel is connected to la second intermediate gear wheel 33 by means of intermediate spur gears 34 and 35, which are mounted on a swinging arm 36. The airis about which this arm swings is coincident with the axis of. the gear wheel. 33, and at its lower end the arm is provided with a slot 37, through which projects a bolt 38 provided i with a locknut Upon loosening this nut 39 the arm 36 can be swung so as to adjust the spur gears 34 and 35 to compensate for the adjustment in taking up the wear on the idler roll. At its upper end the second intermediate 'gear wheel 33 meshes with the gear wheel 24 of the cutter head shaft 23, and through the train of gears above described, the shaft 23 is driven ifrom the shaft 26.

^ The drawoff rolls 5 and 6 are also driven from the shaft 26, the rolls being provided with intermeshing gears 4l and 42 which are driven from the intermediate gear wheel 33 as follows: Mounted on the supplemental frame 17 isan intermediate gear 43, which meshes with a gear 42 and also with a gear wheel 44, the latter as shown in Fig. 3, being sufficiently thick to intermesh with both the gear wheel 43 and the intermediate gear 33 so that the movement of the latter is imparted through the gears 44, 43, 42 and 4l to the drawing off rolls. The proportioning of the chain of gears above described is such that the drawing off gears pull the sheet across the idler roll 4 at a speed so related to that of the cutter head roll that the knife members of the latter will completely sever the pieces from the marginal edges of the sheet without any danger of tearing, it being understood that the surface of the idler roll which serves as a bed for the cutting knives is of such material as to permit the knife blades cutting through and making a clean cut in the roofing sheet.

The detailed construction of the cutting members is shown in Figs. 4 and 5, and comu prises parallelly arranged knife members 46 and 47, which are spaced to receive a spring member 48. The portions 0f these adj ustin cutting members which are brought into engagement with the feed roll 4 are beveled to provide cutting edges 49 and 50the total width between the cutting edges/'being the desired width of the strip which is to be ,removed from the sheet. At ftheir .ends nearest the center of the sheet, the space between the knife members 46 and 47 is closed by ashort transversely extending knifel member 51, which will sever the end of the oblong portion 45, the sides of which are cut by the knife members 46 and 47. lThe knives 46 and 47 are. securpd to the respective 'arms 52 df the' cutterhead4 by means of bolts' 53 and 54 extending through slots l55 and 56. j l

In order to prevent the cutout portions 45 from clogging up the cutter knives, the' the center. If desired, the slitting rolls can be provided with a mutilated portion 59, which at spaced intervals in the sheet will leave narrow connecting portions for holding the two strips together, it being under stood that in this case the user would completely sever the two strips by simply cutting the narrow connecting portions. The completed product, which comprises two of the strips each having a plane edge and a coated edge, is then rewound in a roll 9 upon a shaft 60, which shaft as well as the slitting rolls 7 and 8 can be driven by any suitable connection (not shown) to the main drive shaft 26.

The shaft which carries the cutter heads is mounted lin sliding blocks 6l and 62- which are suspended from a lifting shaft 63 by means of links 64 and 65, and in addition to the adjustment provided for the carrier roll, the position of the cutter head relative to the idler roll can be adjusted by means of a hand wheel 66, which has a screw threaded engagement ,with the lifting shaft llt wil vbe noticed that the action of the two cutter heads is simultaneous but thanthe mounting of the cutter knives of each other head and it is therefore possible on the machine to simultaneously produce from the same double wldth roll of roofing a pair lli@ recante of strips having dierent designs cut from their exposed edges, the strips when used beingr laid in overlapping courses with the cutout edges forming the lower or exposed edge of the strip.

Moreover, the use of the independent cutter heads permits .the cutout or exposed edges of the strips being so formed that the original outer edge of the roofing sheet can be retained as the lower or exposed edge of the rootingn strips when laid. Also in rewinding the strips, the edges having;r the slots` (Sh and 69 are at the outer edges of the roll while the abutting edgcsof the two strips, if rewound in a single roll, are the edges, which when laid, will be concealed andthe machine is therefore capable of producing a new and improved type of rooing'package. i
